docs(tasks): decompose wave 5 — core validation & release
Eight task files under tasks/implementation/core/ (review 005's
dispositions absorbed; no remediation wave):
- core/w5-session-split — review 005 R-1 first (flat siblings +
helper dedups + R-3's constants; zero public-API change)
- core/w5-size-bomb-bound — review 004 R-2 pre-publish (the cap
shape decision + the doubles' incremental inflate + the
hostile-declared-size regression)
- core/w5-oq19-positive-acks / core/w5-oq19-real-client-tokens —
OQ-19 riders 2 and 3; rider 1 executes as the existing
architecture/n5-unborn-head-rider (the tracker's depends_on now
spans all three)
- core/w5-fuzz-harness — the fuzz/ sidecar + targets over R-5's
inventory + the corpus gate joining the verification list
- core/w5-release-readiness — crate docs, feature matrix,
CHANGELOG/README creation, publish dry-run
- core/review-wave-5 — the release gate (OQ-19 dispositions, corpus
gate, size-bomb disposition, the counting-reader decision, N-1's
read, the OQ-03 freeze inventory)
- core/w5-publish — the publish checklist over the gate (manifest
sanity + 0.1.0 bump, tests, CHANGELOG check, dry-run, the
crate-qualified alkgit-v0.1.0 tag, cargo publish)
Plan updated: wave-5 decomposition record + flagged interpretations,
the review-gates bullet, wave-5 status decomposed. taskgraph validate
(54 tasks) green.
